Abstract
The utility model discloses a container with electric label which eliminates negative impact of metal dielectric on the surface of the container and improves the reading effect of the label. The utility model applies the following technical proposal: a container is equipped with electric label which is arranged with aerial and chip on the base plate and positioned on the surface of the plastic jacket of the ventilation opening. Comparing with the present technology, the container equipped with electric label on the surface of the plastic jacket of the ventilation opening to take metal surface of the container as reflection plate not only eliminates the negative impact of the metal dielectric on the surface of the container, but superposes the electromagnetic field reflecting by the metal surface and the field of the label aerial in the far-field of the vertical label to improve the reading effect of the label.
Description
Technical field
The utility model relates to a kind of electronic tag, the electronic identification label that particularly a kind of container is used.
Background technology
Radio-frequency (RF) identification is a kind of of short-wave communication tedhnology, owing to it has at a distance, the ability of Dynamic Recognition, is adopted by increasing industry, wherein also comprises the container cargo distribution management.Because container surface is made of metal, when transmitting on its surface, electromagnetic wave can be absorbed and reflection by metal, thereby cause the ordinary electronic label can't be correctly validated at container surface, for making label energy operate as normal, common way is to make label and container surface keep certain height at present, generally all more than 3cm, and can bring problems such as cost increase, unstable properties, installation and processing inconvenience, the influence of label be attractive in appearance like this.Thereby, how to design a kind of low cost, low section, at the electronic tag that container surface uses, become an outstanding problem of container cargo distribution management.
Summary of the invention
The purpose of this utility model provides a kind of container that has electronic tag, and the technical matters that solve is to eliminate the negative effect of container surface metal medium, improves the effect that reads of label.
The utility model is by the following technical solutions: a kind of container that has electronic tag, and the substrate of electronic tag is provided with antenna and chip, and described electronic tag is installed on the surface of container ventilating opening plastic jacket.
Electronic tag of the present utility model is installed on the inside surface of container ventilating opening plastic jacket.
Electronic tag of the present utility model stick with glue or screw retention at the inside surface of container ventilating opening plastic jacket.
Chip of the present utility model is the radio-frequency card chip that is operated in microwave frequency band.
Antenna of the present utility model is printed on the lead that forms on the substrate by copper-clad plate etching or silver slurry.
Antenna form of the present utility model is half-wave doublet or folded dipole antenna, and antenna length is between 50～90mm, and width is between 30～60mm.
Chip of the present utility model adopts the mode of bonding, upside-down mounting or welding to be connected with electronic label antenna.
Substrate of the present utility model is pcb board or paper card.
The utility model compared with prior art, the electronic tag of container is installed in container ventilating opening plastic jacket inside surface, the container surface metal is as Reflector Panel, not only eliminated the negative effect of container surface metal medium, and can make the electromagnetic field of metal covering reflection realize stack in the far field of vertical label with the field of label antenna, improve the effect that reads of label.
Description of drawings
Fig. 1 has the container embodiment synoptic diagram of electronic tag for the utility model.
Fig. 2 is the upward view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.As depicted in figs. 1 and 2, can in the container cargo distribution management process, well use in order to make electronic tag, the container 1 that has electronic tag of the present utility model has been selected the installation site of container ventilating opening plastic jacket 2 inside surfaces as label, with pcb board or paper card as label substrate, the lead that is printed on the substrate by copper-clad plate etching or silver slurry forms antenna, antenna form is half-wave doublet or folded dipole antenna, the radio-frequency card chip of microwave frequency band passes through bonding, the mode of upside-down mounting or welding is connected with electronic label antenna, sticks with glue or screw is fixed on electronic tag the inside surface of container ventilating opening plastic jacket again.With the container surface metal as Reflector Panel, not only eliminated the negative effect of container surface metal medium, and can make the electromagnetic field of metal covering reflection realize stack in the far field of vertical label with the field of label antenna, reach the effect that distance further improves that reads of label.
From the transmission principle of microwave as can be known, in order to make antenna that higher emission or receiving efficiency be arranged, the physical dimension of antenna should be suitable with the wavelength of its work, typical case is the long or half-wavelength antenna of all-wave, at uhf band, with near the microwave the 900MHz frequency is example, its all-wave vast of heaven line length is greater than 300mm, half-wavelength antenna length is greater than 150mm, this length can not satisfy the requirement of the container that has electronic tag, and antenna form of the present utility model is the distortion of half-wave dipole antenna, and the one end is closed polygon, the other end is the form of meander line, by the width of change level and vertical direction antenna, the size of regulating electric field component is by changing the length of antenna, regulate the size of antenna impedance, reach good coupling between antenna and the chip thereby make.In order to be installed on ventilating opening plastic jacket inboard, the antenna length of label antenna is between 50～90mm, width is between 30～60mm, after debugging, obtain a desirable label antenna form, mode by bonding, upside-down mounting or welding is connected chip with electronic label antenna at last, obtains having the container of electronic tag.
The utility model has utilized the original ventilating opening plastic jacket of container, electronic tag is installed in the inside surface of plastic jacket, by regulating the impedance and the tuning-points of distortion dipole antenna, make antenna in the frequency of operation of system, have good performance on the one hand, the opposing party can utilize the height of ventilating opening plastic jacket, make the metal of container surface become the part of antenna, thereby the performance of antenna will be excellent more, eliminated the negative effect of container surface metal medium, improved the distance that reads of label, and has a stable performance, fabrication and installation are convenient, good concealment, advantage such as with low cost is for the microwave electron label provides a good solution in the container automatic management is used.
Embodiment, the shape of label antenna substrate and be of a size of 75mm * 45mm * 1mm, label antenna in substrate front side silk-screen or etching, adopt black conductive glue together, label is affixed on the inside surface of container ventilating opening plastic jacket with glue radio-frequency card IC chip pin and on-chip silk-screen circuit package.
